The aim of the study was to assess interdependence of specific motor abilities (situation karate tests) and motor skills (karate techniques), and karate performance (fighting efficiency) in under-sixteen male karateka aged 11-12 and 13-14 years. A battery of 5 situation motor tests were applied and 6 basic elements of karate technique evaluated in a sample of 20 male karateka aged 11-12 and 20 male karateka aged 13-14 years. Three criterion variables were formed: 1) one factor as a factor of general technical efficiency in karate was isolated by factor analysis of 6 karate techniques; 2) cumulative evaluation of 2 kate as kate performance; and 3) total score assessment based on success achieved at national karate championships as contest efficiency (fighting efficiency).

Ninety-six percent of K-Sol grafts (n = 51) and 94% of the CSM grafts (n = 51) were clear at 6 months; 92% of both the K-Sol (n = 38) and CSM (n = 35) grafts were clear at 12 months. One primary donor failure occurred, a K-Sol cornea stored for 76 hours.

Compared to age-matched controls, a significant increase in mean endothelial permeability was found in the contact lens group, indicating a defect in their endothelial barrier function. A significant increase in the mean endothelial pump rate was also noted in the contact lens group.
